RESUMO

BACKGROUND: Recent data suggest patients with graft failure had better access to repeat kidney transplantation (re-KT) than transplant-naive dialysis accessing first KT. This was postulated to be because of better familiarity with the transplant process and healthcare system; whether this advantage is equitably distributed is not known. We compared the magnitude of racial/ethnic disparities in access to re-KT versus first KT. METHODS: Using United States Renal Data System, we identified 104 454 White, Black, and Hispanic patients with a history of graft failure from 1995 to 2018, and 2 357 753 transplant-naive dialysis patients. We used adjusted Cox regression to estimate disparities in access to first and re-KT and whether the magnitude of these disparities differed between first and re-KT using a Wald test. RESULTS: Black patients had inferior access to both waitlisting and receiving first KT and re-KT. However, the racial/ethnic disparities in waitlisting for (adjusted hazard ratio [aHR] = 0.77; 95% confidence interval [CI], 0.74-0.80) and receiving re-KT (aHR = 0.61; 95% CI, 0.58-0.64) was greater than the racial/ethnic disparities in first KT (waitlisting: aHR = 0.91; 95% CI, 0.90-0.93; Pinteraction = 0.001; KT: aHR = 0.68; 95% CI, 0.64-0.72; Pinteraction < 0.001). For Hispanic patients, ethnic disparities in waitlisting for re-KT (aHR = 0.83; 95% CI, 0.79-0.88) were greater than for first KT (aHR = 1.14; 95% CI, 1.11-1.16; Pinteraction < 0.001). However, the disparity in receiving re-KT (aHR = 0.76; 95% CI, 0.72-0.80) was similar to that for first KT (aHR = 0.73; 95% CI, 0.68-0.79; Pinteraction = 0.55). Inferences were similar when restricting the cohorts to the Kidney Allocation System era. CONCLUSIONS: Unlike White patients, Black and Hispanic patients with graft failure do not experience improved access to re-KT. This suggests that structural and systemic barriers likely persist for racialized patients accessing re-KT, and systemic changes are needed to achieve transplant equity.

RESUMO

The 20th century has witnessed the development of tissue and organ transplantation as the best therapeutic option for end-stage organ failure; however, organ shortages remain a prominent worldwide issue. Donation after circulatory death is an accepted practice in several countries around the world but also poses many challenges. Presently, controlled donations after circulatory death are not really in practice in Turkey and the Middle East, and the implementation of this practice seems complicated. To gather information about the possible reasons underlying the lack of organs from donors after circulatory death, as well as solutions, a discussion session took place during the International Symposium on "Brain Death and Circulatory Death" on November 29-30, 2023, in Ankara, Turkey. A description on different topics that were discussed is presented.

RESUMO

Background: It can be difficult for kidney transplant recipients (KTRs) to be physically active after their transplantation. Physical inactivity is a risk factor for cardiovascular disease, one of the leading cause of death among KTRs. To help KTRs start and maintain a physical activity routine, we developed the KEeP ACTIVe Club, a 6-month online intervention with access to a kinesiologist, a patient partner, and a private support group with an online platform (Facebook). Objective: The objective of this study was to capture the participants' experiences of the KEeP ACTIVe Club. Design: Individual interviews. Setting: The Center hospitalier de l'Université de Montréal (CHUM) and the McGill University Health Center (MUHC) kidney transplant programs. Participants: Kidney transplant recipients who participated in the KEeP ACTIVe Club. Methods: Between October and December 2021, we conducted 11 individual semi-directed interviews with KTRs from 2 urban kidney transplant programs who participated in the KEeP ACTIVe Club. The interviews were digitally recorded and transcribed. Thematic analysis was conducted. Results: Participants' principal motivation to participate in the KEeP ACTIVe Club was to improve their physical fitness following their transplant in a pandemic period. One of the main benefits of the KEeP ACTIVe Club was the improvement of participant's self-confidence and the knowledge gained regarding exercises adapted to their reality as KTRs. However, the small number of participants and the schedules of classes offered were viewed as a pitfall of the current intervention. Finally, the peer mentoring and support gained by other participants were important and viewed as highly impactful aspects of the KEeP ACTIVe Club. Limitations: Only 11 of the 18 patients who participated in the KEeP ACTIVe Club took part in the interviews. Conclusion: Participants reported a positive experience with the KEeP ACTIVe Club. Peer mentoring and support gained from other participants seem to be essential aspects of the experience within the KEeP ACTIVe Club. This program is a good avenue to offer in post-transplant care to help KTRs to be more active and to connect with other patients.


Contexte: Il peut être difficile pour les receveurs d'une greffe de rein d'être actifs physiquement après la transplantation. L'inactivité est un facteur de risque de maladie cardiovasculaire, une des principales causes de décès chez les greffés du rein. Afin d'aider ces patients à entreprendre une routine d'activité physique et à la maintenir, nous avons développé le KEeP ACTIVe Club, une intervention en ligne d'une durée de six mois qui donne accès à un kinésiologue, à un patient partenaire et à un groupe privé de soutien par le biais d'une plateforme en ligne (Facebook). Objectifs: Connaître l'expérience des participants au KEeP ACTIVe Club. Conception: Entretiens individuels. Cadre: Les programme de transplantation rénale du Center hospitalier de l'Université de Montréal (CHUM) et du Centre universitaire de santé McGill (CUSM). Participants: Des receveurs d'une greffe de rein ayant participé au KEeP ACTIVe Club. Méthodologie: Entre octobre et décembre 2021, nous avons mené 11 entretiens individuels semi-dirigés avec des receveurs d'une greffe rénale qui ont participé au KEeP ACTIVe Club dans deux programmes de transplantation en center urbain. Les entretiens ont été enregistrés en mode numérique, transcrits, puis une analyze thématique a été réalisée. Résultats: La principale motivation des receveurs à participer au KEeP ACTIVe Club était d'améliorer leur condition physique après la greffe, en période pandémique. Les principaux avantages d'avoir participé au KEeP ACTIVe Club ont été l'augmentation de la confiance en soi et l'acquisition de connaissances sur des exercices adaptés à leur réalité de greffés du rein. Le faible nombre de participants et l'horaire des cours proposés ont été perçus comme des faiblesses de l'intervention. Enfin, le mentorat par les pairs et le soutien reçu des autres participants ont été jugés importants et perçus comme des aspects très positifs du KEeP ACTIVe Club. Limites: Sur les dix-huit patients inscrits au KEeP ACTIVe Club, seuls onze ont participé aux entrevues. Conclusion: Les participants ont déclaré avoir eu une expérience positive avec le KEeP ACTIVe Club. Le mentorat par les pairs et le soutien reçu des autres participants semblent être des aspects essentiels de l'expérience positive vécue au sein du KEeP ACTIVe Club. Ce programme est une bonne avenue à proposer dans les soins post-transplantation pour aider les greffés du rein à être plus actifs physiquement et à échanger avec d'autres patients.

RESUMO

Rationale: Cryptococcal-immune reconstitution inflammatory syndrome (C-IRIS) is a rare but recognized clinical entity in solid organ transplant recipients, though its clinical course and sequelae remain largely poorly described. Presenting Concerns of the Patient: We present the case of a kidney transplant recipient who presented with headache and fever. A cerebrospinal fluid analysis was performed and found to be compatible with cryptococcal meningitis. After down titration of immunosuppression and antifungal initiation, the patient initially improved. Weeks later, they experienced a sudden deterioration in mental status, prompting admission to the intensive care unit (ICU). Diagnosis: This deterioration was attributed to C-IRIS, which developed following rapid de-escalation of immunosuppression in response to the diagnosis of cryptococcal meningitis. Interventions: The initial episode of C-IRIS responded well to high-dose steroids; however, maintenance immunosuppression was not increased. Outcomes: Within 2 months, the patient presented again to the hospital with a pulmonary infiltrate and multifocal ischemic strokes. Novel Findings: We argue this to be a case of relapsing multisystem C-IRIS, thus expanding the known spectrum of manifestations of C-IRIS in renal transplant recipients. We propose that following the diagnosis of C-IRIS, maintenance immunosuppression be escalated to avoid the risk of relapse and inflammatory-mediated organ dysfunction.


Justification: Le syndrome inflammatoire de reconstitution immunitaire dû au cryptocoque (C-IRIS) est une entité clinique rare, mais reconnue chez les receveurs d'une greffe d'organe solide. Son évolution clinique et les séquelles qu'il engendre demeurent cependant largement mal décrites. Présentation du cas: Nous présentons le cas d'un receveur d'une greffe rénale qui souffrait de céphalées et de fièvre. L'analyze du liquide céphalo-rachidien du patient était compatible avec une méningite cryptococcique. La réduction de la dose du traitement immunosuppresseur et l'initiation d'un traitement antifongique ont d'abord permis d'améliorer l'état général du patient. Son état mental s'est toutefois détérioré quelques semaines plus tard, ce qui a nécessité son admission à l'unité de soins intensifs (USI). Diagnostic: Cette détérioration a été attribuée au C-IRIS, lequel s'est développé à la suite de la désescalade rapide de l'immunosuppression en réponse au diagnostic de méningite cryptococcique. Intervention: L'épisode initial de C-IRIS a bien répondu à une dose élevée de stéroïdes; l'immunosuppression d'entretien n'a cependant pas été augmentée. Résultats: Le patient s'est de nouveau présenté à l'hôpital dans les deux mois suivants avec un infiltrat pulmonaire et des accidents vasculaires cérébraux ischémiques multifocaux. Principales observations: Nous soutenons qu'il s'agit d'un cas de C-IRIS récidivant affectant plusieurs systèmes, ce qui élargit le specter des manifestations connues du C-IRIS chez les transplantés rénaux. Nous suggérons que le traitement immunosuppresseur d'entretien soit intensifié après un diagnostic de C-IRIS afin d'éviter les risques de rechute et de dysfonctionnement des organes à médiation inflammatoire.

RESUMO

Organ and tissue donation and transplantation (OTDT) legislation and policies vary around the world, and this variability contributes to discrepancies in system performance. This article describes the purpose and methodology of an international forum that was organized to create consensus recommendations related to key legal and policy attributes of an ideal OTDT system. The intent is to create guidance for legislators, regulators, and other system stakeholders who aim to create or reform OTDT legislation and policy. Methods: This Forum was initiated by Transplant Québec and cohosted by the Canadian Donation and Transplantation Program partnered with multiple national and international donation and transplantation organizations. Seven domains were identified by the scientific committee' and domain working groups identified specific topics for recommendations: Baseline Ethical Principles, Legal Foundations, Consent Model and Emerging Legal Issues, Donation System Architecture, Living Donation, Tissue Donation, and Research and Innovation Systems and Emerging Issues. Patient, family, and donor partners were integrated into every stage of the planning and execution of the Forum. Sixty-one participants from 13 countries contributed to recommendation generation. Topic identification and recommendation consensus was completed over a series of virtual meetings from March to September 2021. Consensus was achieved by applying the nominal group technique informed by literature reviews performed by participants. Recommendations were presented at a hybrid in-person and virtual forum in Montreal, Canada, in October 2021. Output: Ninety-four recommendations (9-33 per domain) and an ethical framework for evaluating new policies were developed during the Forum proceedings. The accompanying articles include the recommendations from each domain and justifications that link the consensus to existing literature and ethical or legal concepts. Conclusions: Although the recommendations could not account for the vast global diversity of populations, healthcare infrastructure, and resources available to OTDT systems, they were written to be as widely applicable as possible.

RESUMO

BACKGROUND: Living donor kidney transplantation (LDKT) is the best treatment option for patients with kidney failure and offers significant medical and economic advantages for both patients and health systems. Despite this, rates of LDKT in Canada have stagnated and vary significantly across Canadian provinces, the reasons for which are not well understood. Our prior work has suggested that system-level factors may be contributing to these differences. Identifying these factors can help inform system-level interventions to increase LDKT. OBJECTIVE: Our objective is to generate a systemic interpretation of LDKT delivery across provincial health systems with variable performance. We aim to identify the attributes and processes that facilitate the delivery of LDKT to patients, and those that create barriers and compare these across systems with variable performance. These objectives are contextualized within our broader goal of increasing rates of LDKT in Canada, particularly in lower-performing provinces. METHODS: This research takes the form of a qualitative comparative case study analysis of 3 provincial health systems in Canada that have high, moderate, and low rates of LDKT performance (the percentage of LDKT to all kidney transplantations performed). Our approach is underpinned by an understanding of health systems as complex adaptive systems that are multilevel and interconnected, and involve nonlinear interactions between people and organizations, operating within a loosely bounded network. Data collection will comprise semistructured interviews, document reviews, and focus groups. Individual case studies will be conducted and analyzed using inductive thematic analysis. Following this, our comparative analysis will operationalize resource-based theory to compare case study data and generate explanations for our research question. RESULTS: This project was funded from 2020 to 2023. Individual case studies were carried out between November 2020 and August 2022. The comparative case analysis will begin in December 2022 and is expected to conclude in April 2023. Submission of the publication is projected for June 2023. CONCLUSIONS: By investigating health systems as complex adaptive systems and making comparisons across provinces, this study will identify how health systems can improve the delivery of LDKT to patients with kidney failure. Our resource-based theory framework will provide a granular analysis of the attributes and processes that facilitate or create barriers to LDKT delivery across multiple organizations and levels of practice. Our findings will have practice and policy implications and help inform transferrable competencies and system-level interventions conducive to increasing LDKT.

RESUMO

Repeat kidney transplantation (re-KT) is the preferred treatment for patients with graft failure. Changing allocation policies, widening the risk profile of recipients, and improving dialysis care may have altered the survival benefit of a re-KT. We characterized trends in re-KT survival benefit over 3 decades and tested whether it differed by age, race/ethnicity, sex, and panel reactive assay (PRA). By using the Scientific Registry of Transplant Recipient data, we identified 25 419 patients who underwent a re-KT from 1990 to 2019 and 25 419 waitlisted counterfactuals from the same year with the same waitlisted time following graft failure. In the adjusted analysis, a re-KT was associated with a lower risk of death (adjusted hazard ratio [aHR] = 0.63; 95% confidence interval [CI], 0.61-0.65). By using the 1990-1994 era as a reference (aHR = 0.77; 95% CI, 0.69-0.85), incremental improvements in the survival benefit were noted (1995-1999: aHR = 0.72; 95% CI, 0.67-0.78: 2000-2004: aHR = 0.59; 95% CI, 0.55-0.63: 2005-2009: aHR = 0.59; 95% CI, 0.56-0.63: 2010-2014: aHR = 0.57; 95% CI, 0.53-0.62: 2015-2019: aHR = 0.64; 95% CI, 0.57-0.73). The survival benefit of a re-KT was noted in both younger (age = 18-64 years: aHR = 0.63; 95% CI, 0.61-0.65) and older patients (age ≥65 years: aHR = 0.66; 95% CI, 0.58-0.74; Pinteraction = .45). Patients of all races/ethnicities demonstrated similar benefits with a re-KT. However, it varied by the sex of the recipient (female patients: aHR = 0.60; 95% CI, 0.56-0.63: male patients: aHR = 0.66; 95% CI, 0.63-0.68; Pinteraction = .004) and PRA (0-20: aHR = 0.69; 95% CI, 0.65-0.74: 21-80: aHR = 0.61; 95% CI, 0.57-0.66; Pinteraction = .02; >80: aHR = 0.57; 95% CI, 0.53-0.61; Pinteraction< .001). Our findings support the continued practice of a re-KT and efforts to overcome the medical, immunologic, and surgical challenges of a re-KT.

RESUMO

The pharmacotherapeutic management of people living with HIV (PLWHIV) undergoing solid organ transplantation (SOT) is clinically challenging, mainly due to the frequent occurrence of complex drug-drug interactions. Although various strategies have been proposed to improve treatment outcomes in these patients, several uncertainties remain, and consensus practice guidelines are just beginning to emerge. The main objective of this scoping review was to map the extent of the literature on the pharmacotherapeutic interventions performed by healthcare professionals for PLWHIV undergoing SOT. Methods: We searched Medline, Embase, and the Cochrane databases as well as gray literature for articles published between January 2010 and February 2020. Study selection was performed by at least 2 independent reviewers. Articles describing pharmacotherapeutic interventions in PLWHIV considered for or undergoing SOT were included in the study. Results: Of the 12 599 references identified through our search strategy, 209 articles met the inclusion criteria. Results showed that the vast majority of reported pharmacotherapeutic interventions concerned the management of immunosuppressive and antimicrobial therapy, including antiretrovirals. Analysis of the data demonstrated that for several aspects of the pharmacotherapeutic management of PLWHIV undergoing SOT, there were differing practices, such as the choice of immunosuppressive induction and maintenance therapy. Other important aspects of patient management, such as patient counseling, were rarely reported. Conclusions: Our results constitute an extensive overview of current practices in the pharmacotherapeutic management of SOT in PLWHIV and identify knowledge gaps that should be addressed to help improve patient care in this specific population.

RESUMO

Background: Patients with kidney failure represent a major public health burden, and living donor kidney transplantation (LDKT) is the best treatment option for these patients. Current work to optimize LDKT delivery to patients has focused on microlevel interventions and has not addressed interdependencies with meso and macro levels of practice. Objective: We aimed to learn from a health system with historically low LDKT performance to identify facilitators and barriers to LDKT. Our specific aims were to understand how LDKT delivery is organized through interacting macro, meso, and micro levels of practice and identify what attributes and processes of this health system facilitate the delivery of LDKT to patients with kidney failure and what creates barriers. Design: We conducted a qualitative case study, applying a complex adaptive systems approach to LDKT delivery, that recognizes health systems as being made up of dynamic, nested, and interconnected levels, with the patient at its core. Setting: The setting for this case study was the province of Quebec, Canada. Participants: Thirty-two key stakeholders from all levels of the health system. This included health care professionals, leaders in LDKT governance, living kidney donors, and kidney recipients. Methods: Semi-structured interviews with 32 key stakeholders and a document review were undertaken between February 2021 and December 2021. Inductive thematic analysis was used to generate themes. Results: Overall, we identified strong links between system attributes and processes and LDKT delivery, and more barriers than facilitators were discerned. Barriers that undermined access to LDKT included fragmented LDKT governance and expertise, disconnected care practices, limited resources, and regional inequities. Some were mitigated to an extent by the intervention of a program launched in 2018 to increase LDKT. Facilitators driven by the program included advocacy for LDKT from individual member(s) of the care team, dedicated resources, increased collaboration, and training opportunities that targeted LDKT delivery at multiple levels of practice. Limitations: Delineating the borders of a "case" is a challenge in case study research, and it is possible that some perspectives may have been missed. Participants may have produced socially desirable answers. Conclusions: Our study systematically investigated real-world practices as they operate throughout a health system. This novel approach has cross-disciplinary methodological relevance, and our findings have policy implications that can help inform multilevel interventions to improve LDKT.


Contexte: Les patients atteints d'insuffisance rénale représentent un lourd fardeau pour la santé publique, et la transplantation rénale provenant d'un donneur vivant (TRDV) est la meilleure option de traitement pour ces patients. Les travaux actuels visant à optimiser la TRDV chez les patients ont été limités à des interventions de niveau micro et n'ont pas abordé les interdépendances avec les niveaux méso et macro de la pratique. Objectifs: Notre objectif était d'apprendre d'un système de santé présentant un taux historiquement bas de TRDV pour arriver à déterminer les facteurs qui constituent un facilitateur ou un frein à la TRDV. Plus précisément, nous souhaitions, par le biais d'interactions entre les niveaux macro, méso et micro de la pratique, comprendre la façon dont la TRDV est organisée. Nous souhaitions également déterminer quels attributs et processus du système de santé constituent des facilitateurs ou des freins à la TRDV pour les patients atteints d'insuffisance rénale. Conception: Nous avons appliqué une approche de systèmes adaptatifs complexes à la TRDV pour mener une étude de cas qualitative qui reconnaît que les systèmes de santé sont constitués de niveaux dynamiques, imbriqués et interconnectés, où le patient est au cœur des interventions. Cadre: Cette étude de cas avait pour cadre la province de Québec (Canada). Participants: 32 intervenants clés de tous les niveaux du système de santé, notamment des professionnels de la santé, des leaders impliqués dans la gestion de la TRDV, des donneurs vivants d'un rein et des receveurs de rein. Méthodologie: Des entrevues semi-structurées avec 32 intervenants clés et un examen des documents ont été entrepris entre février 2021 et décembre 2021. L'analyse thématique inductive a servi à générer les thèmes. Résultats: De façon générale, nous avons constaté qu'il existait des liens solides entre la TRDV et les attributs et processus du système, et que les obstacles étaient plus nombreux que les facilitateurs. Les obstacles freinant l'accès à la TRDV comprenaient la gouvernance et l'expertise fragmentées en lien avec la TRDV, les pratiques de soins déconnectées, les ressources limitées et les inégalités régionales. Certains de ces obstacles ont été atténués dans une certaine mesure par l'intervention d'un programme lancé en 2018 pour accroître la TRDV. Les facilitateurs soutenus par le programme comprenaient la promotion de la TRDV par des membres individuels de l'équipe de soins, la disponibilité de ressources dédiées, une collaboration accrue et les possibilités de formation ciblant la TRDV à plusieurs niveaux de pratique. Limites: La délimitation des frontières de ce que constitue un « cas ¼ est un défi dans la recherche d'études de cas; il est ainsi possible que certaines perspectives aient été manquées. Les participants pourraient avoir donné des réponses socialement souhaitables. Conclusion: Notre étude a examiné systématiquement les pratiques en contexte réel, tel qu'elles fonctionnent dans l'ensemble d'un système de santé. Cette nouvelle approche présente une pertinence méthodologique interdisciplinaire et nos conclusions ont des implications politiques qui pourraient aider à orienter des interventions à plusieurs niveaux pour améliorer la TRDV.

RESUMO

Introduction: Studying existing health systems with variable living donor kidney transplantation (LDKT) performance and understanding factors that drive these differences can inform comprehensive system-level approaches to improve LDKT. We aimed to quantify previously identified barriers and estimate their association with LDKT performance. Methods: We conducted a cross-sectional survey of health professionals (HPs). Statements, rated on a Likert scale of "strongly disagree" to "strongly agree", captured themes related to communication; role perception; HP's education, training and comfort; attitudes; referral process; patient; as well as resources and infrastructure. The percentage who agreed with these statements was analyzed and compared by LDKT performance (living donation rates higher or lower than the national average) and participant characteristics. Results: We obtained 353 complete responses. Themes related to poor communication, poor role perception, and HPs education or training or comfort emerged as barriers to LDKT. When compared with HPs from high-performing provinces, those from low-performing provinces had lower odds of agreeing that their province promoted LDKT (adjusted odd ratio [aOR] = 0.27, 95% confidence interval [CI]: 0.16-0.48). They also had lower odds of initiating discussions about LDKT (aOR = 0.30, 95% CI: 0.17-0.55), and higher odds of agreeing that the transplant team is best suited to discuss LDKT (aOR = 2.64, 95% CI: 1.60-4.33) and that more resources would increase LDKT discussions (aOR = 2.06, 95% CI: 1.25-3.40). Nonphysician role and less than 10 years of experience were associated with the level of agreement across several themes. Creating guidelines, streamlining evaluations, and improving communication were ranked as priorities to increase LDKT. Conclusion: There are system-level barriers to LDKT and some were more prevalent in low-performing provinces. Interventions to eliminate them should be implemented in conjunction with patient-level interventions as part of a comprehensive system-level approach to increase LDKT.

RESUMO

BACKGROUND: Transplant therapy is considered the best and often the only available treatment for thousands of patients with organ failure that results from communicable and noncommunicable diseases. The number of annual organ transplants is insufficient for the worldwide need. METHODS: We elaborate the proceedings of the workshop entitled "The Role of Science in the Development of International Standards of Organ Donation and Transplantation," organized by the Pontifical Academy of Sciences and cosponsored by the World Health Organization in June 2021. RESULTS: We detail the urgency and importance of achieving national self-sufficiency in organ transplantation as a public health priority and an important contributor to reaching relevant targets of the United Nations Agenda for Sustainable Development. It details the elements of a global action framework intended for countries at every level of economic development to facilitate either the establishment or enhancement of transplant activity. It sets forth a proposed plan, by addressing the technical considerations for developing and optimizing organ transplantation from both deceased and living organ donors and the regulatory oversight of practices. CONCLUSIONS: This document can be used in governmental and policy circles as a call to action and as a checklist for actions needed to enable organ transplantation as treatment for organ failure.

RESUMO

INTRODUCTION: Neutropenia post-kidney transplantation is associated with adverse graft and patient outcomes. We aimed to analyze the effect of granulocyte colony-stimulating factor (G-CSF) use with and without immunosuppression reduction on graft outcomes in neutropenic recipients. METHODS: In this retrospective cohort study, we identified 120 recipients with neutropenia, within the first-year post-transplant. RESULTS: Of these, 45.0% underwent no intervention, 17.5% had immunosuppression reduced, 18.3% were only given G-CSF, and 19.2% had both interventions. Overall, 61 patients experienced the composite outcome of de-novo DSA, biopsy-proven acute rejection, and all-cause graft failure and the cumulative incidence of this outcome did not vary by any of the four interventions (p = .93). When stratifying the cohort by G-CSF use alone, those who received G-CSF were more likely to have had severe neutropenia (<500/mm3 : 51.1% vs. 12.0%, p < .001), and immunosuppression reduction (51.1% vs. 28.0%, p = .003). However, the composite outcome was not different in the G-CSF and no G-CSF cohort (53.3% vs. 49.3%, p = .67), and in a multivariate model, G-CSF use was not associated with this outcome (aHR = 1.18, 95% CI: .61-2.30). However, a trend towards higher DSA production was noted in the G-CSF cohort (87.5% vs. 62.2%) and this observation warrants prospective evaluation. CONCLUSION: Overall, we conclude that G-CSF use with or without immunosuppression reduction was not associated with graft outcomes.

RESUMO

BACKGROUND: In kidney transplant recipients (KTRs), observational data have reported conflicting findings about the utility of renal resistive index (RRI) in determining outcomes. This study aimed to synthesize the current literature and determine the prognostic role of RRI in KTRs. METHODS: The authors conducted a systematic review to assess the role of RRI in predicting death, graft failure, graft function and proteinuria. Of the 934 titles/abstracts reviewed, 26 studies were included. There was significant heterogeneity in RRI measurements and thresholds as well as in analytical methods, and a meta-analysis could not be performed. RESULTS: All included studies were observational and included 7049 KTRs. Eight studies analyzed death, of which five reported a significant association with higher RRI. In the remaining three, small sample sizes and lower/multiple RRI thresholds may have limited detection of a statistically significant difference. Three studies investigated all-cause graft failure, and an association with RRI was reported but varied by time of RRI measurement. Three out of five studies that analyzed a composite of patient and graft outcomes reported an association with RRI. Evidence analyzing death-censored graft failure, graft failure (unclear whether death-censored or all-cause), measures of graft function and proteinuria was conflicting. Most studies had a moderate to high risk of bias. CONCLUSIONS: RRI likely has a prognostic role in predicting patient outcomes, reflecting patient systemic vascular disease burden rather than graft hemodynamics. Since cardiovascular diseases are a major cause of death and graft loss, RRI may be explored as a noninvasive tool to risk-stratify KTRs.

RESUMO

BACKGROUND: In patients with kidney failure, living donor kidney transplantation (LDKT) is the best treatment option; yet, LDKT rates have stagnated in Canada and vary widely across provinces. We aimed to identify barriers and facilitators to LDKT in a high-performing health system. METHODS: This study was conducted using a qualitative exploratory case study of British Columbia. Data collection, conducted between October 2020 and January 2021, entailed document review and semistructured interviews with key stakeholders, including provincial leadership, care teams and patients. We recruited participants via purposive sampling and snowballing technique. We generated themes using thematic analysis. RESULTS: After analysis of interviews conducted with 22 participants (5 representatives from provincial organizations, 7 health care providers at transplant centres, 8 health care providers from regional units and 2 patients) and document review, we identified the following 5 themes as facilitators to LDKT: a centralized infrastructure, a mandate for timely intervention, an equitable funding model, a commitment to collaboration and cultivating distributed expertise. The relationship between 2 provincial organizations (BC Transplant and BC Renal Agency) was identified as key to enabling the mandate and processes for LDKT. Five barriers were identified that arose from silos between provincial organizations and manifested as inconsistencies in coordinating LDKT along the spectrum of care. These were divided accountability structures, disconnected care processes, missed training opportunities, inequitable access by region and financial burden for donors and recipients. INTERPRETATION: We found strong links between provincial infrastructure and the processes that facilitate or impede timely intervention and referral of patients for LDKT. Our findings have implications for policy-makers and provide opportunities for cross-jurisdictional comparative analyses.

RESUMO

OBJECTIVES: The COVID-19 pandemic significantly affected the provisions of health services to necessary but deprioritised fields, such as transplantation. Many programmes had to ramp-down their activity, which may significantly affect transplant volumes. We aimed to pragmatically analyse measures of transplant activity and compare them by a country's income level and cumulative COVID-19 incidence (CCI). DESIGN, SETTING AND PARTICIPANTS: From June to September 2020, we surveyed transplant physicians identified as key informants in their programmes. Of the 1267 eligible physicians, 40.5% from 71 countries participated. OUTCOME: Four pragmatic measures of transplant activity. RESULTS: Overall, 46.5% of the programmes from high-income countries anticipate being able to maintain >75% of their transplant volume compared with 31.6% of the programmes from upper-middle-income countries, and with 21.7% from low/lower-middle-income countries (p<0.001). This could be because more programmes in high-income countries reported being able to perform transplantation/s (86.8%%-58.5%-67.9%, p<0.001), maintain prepandemic deceased donor offers (31.0%%-14.2%-26.4%, p<0.01) and avoid a ramp down phase (30.9%%-19.7%-8.3%, p<0.001), respectively. In a multivariable analysis that adjusted for CCI, programmes in upper-middle-income countries (adjusted OR, aOR=0.47, 95% CI 0.27 to 0.81) and low/lower-middle-income countries (aOR 0.33, 95% CI 0.16 to 0.67) had lower odds of being able to maintain >75% of their transplant volume, compared with programmes in high-income countries. Again, this could be attributed to lower-income being associated with 3.3-3.9 higher odds of performing no transplantation/s, 66%-68% lower odds of maintaining prepandemic donor offers and 37%-76% lower odds of avoiding ramp-down of transplantation. Overall, CCI was not associated with these measures. CONCLUSIONS: The impact of the pandemic on transplantation was more in lower-income countries, independent of the COVID-19 burden. Given the lag of 1-2 years in objective data being reported by global registries, our findings may inform practice and policy. Transplant programmes in lower-income countries may need more effort to rebuild disrupted services and recuperate from the pandemic even if their COVID-19 burden was low.

RESUMO

BACKGROUND: In older adults (≥65), access to and outcomes following kidney transplantation (KT) have improved over the past 3 decades. It is unknown if there were parallel trends in re-KT. We characterized the trends, changing landscape, and outcomes of re-KT in older adults. METHODS: Among the 44,149 older kidney-only recipients (1995-2016) in the Scientific Registry of Transplant Recipients, we identified 1743 who underwent re-KT. We analyzed trends and outcomes (mortality, death-censored graft failure [DCGF]) by eras (1995-2002, 2003-2014, and 2015-2016) that were defined by changes to the expanded criteria donors and Kidney Donor Profile Index policies. RESULTS: Among all older kidney-only recipients during 1995-2002, 2003-2014, 2015-2016 the proportion that were re-KTs increased from 2.7% to 4.2% to 5.7%, P < 0.001, respectively. Median age at re-KT (67-68-68, P = 0.04), years on dialysis after graft failure (1.4-1.5-2.2, P = 0.003), donor age (40.0-43.0-43.5, P = 0.04), proportion with panel reactive antibody 80-100 (22.0%-32.7%-48.7%, P < 0.001), and donation after circulatory death (1.1%-13.4%-19.5%, P < 0.001) have increased. Despite this, the 3-y cumulative incidence for mortality (22.3%-19.1%-11.5%, P = 0.002) and DCGF (13.3%-10.0%-5.1%, P = 0.01) decreased over time. Compared with deceased donor retransplant recipients during 1995-2002, those during 2003-2014 and 2015-2016 had lower mortality hazard (aHR = 0.78, 95% confidence interval, 0.63-0.86 and aHR = 0.55, 95% confidence interval, 0.35-0.86, respectively). These declines were noted but not significant for DCGF and in living donor re-KTs. CONCLUSIONS: In older retransplant recipients, outcomes have improved significantly over time despite higher risk profiles; yet they represent a fraction of the KTs performed. Our results support increasing access to re-KT in older adults; however, approaches to guide the selection and management in those with graft failure need to be explored.

RESUMO

Performing third or fourth kidney transplantation (3KT and 4KT) in older patients is rare due to surgical and immunologic challenges. We aimed to analyze and compare the outcomes of younger (18-64 years) and older (≥65 years) recipients of 3KT and 4KT. Between 1990 and 2016, we identified 5816 recipients of 3KTs (153 were older) and 886 recipients of 4KTs (18 were older). The incidences of delayed graft function (24.3% vs. 24.8%, p = .89), primary non-function (3.2% vs. 1.3%, p = .21), 1-year acute rejection (18.6% vs. 14.8%, p = .24), and 5-year death censored graft failure (DCGF) (24.8% vs. 17.9%, p = .06) were not different between younger and older recipients of 3KT. However, 5-year mortality was higher in older recipients (14.0% vs. 33.8%, p < .001) which remained significant after adjustment (aHR = 3.21, 95% CI: 2.59-3.99). Similar patterns were noted in the 4KT cohort. When compared with waitlisted patients, 3KT and 4KT are associated with a lower risk of mortality; aHR = 0.37, 95% CI: 0.33-0.41 and aHR = 0.31, 95% CI: 0.24-0.41, respectively. This survival benefit did not differ by recipient age (younger vs. older, p for interaction = 3KT: .49 and 4KT: .58). In the largest cohort described to date, we report that there is a survival benefit of 3KT and 4KT even among older patients. Although a highly selected cohort, our results support improving access to 3KT and 4KT.

RESUMO

OBJECTIVES: The objective of the present report was to analyze the opinions, attitudes, and practices of Baskent University students with regard to the impact of religion on organ donation and transplantation. MATERIALS AND METHODS: We sent a web-based, 5-point Likert scale questionnaire (1: strongly disagree; 5: strongly agree) to capture the opinions and attitudes toward organ donation and transplantation after participants attended or did not a panel discussion on these topics. RESULTS: We sent 361 E-mails and received 69 responses, of which 46 students attended the panel discussion. Most of the participants who attended were part of the faculty of medicine. Participants who did not attend were composed of students from other faculties at Baskent University. Religion played less of a role with regard to opinions on organ donation in those who did not attend. Of the attendees, 54.3% strongly agreed to become organ donors, 50% believed in the important role of religion in organ donation, and 54.3% believed that media sources play important roles in shaping public opinion on organ donation. The majority felt comfortable discussing organ donation with family and friends. CONCLUSIONS: Although religion has an undeniable effect on the decision-making process, our survey showed that more than half of the participants were willing to become organ donors. Education, through the joint efforts of medical and religious scholars, as well as the media, should contribute to raising awareness on organ donation, thus contributing to increased access to transplantation worldwide.
